CNN has obtained exclusive footage of US President Donald Trump and several people connected to the alleged collusion between his campaign associates and Russia.

The video shows Trump attending a June 15, 2013 dinner with his future business partners, the Azerbaijani-Russian family, and their publicist, Rob Goldstone.

Goldstone is currently caught up in the controversy surrounding Mr Trump’s eldest son and alleged Russian collusion in the election.

The US president’s son, Donald Trump Jr released an email chain earlier on Tuesday in which he said he would “love” to receive damaging information about his father’s Democratic rival, Hillary Clinton, from Russian lawyer Natalia Veselnitskaya.

The video was shot in Las Vegas on the eve of the Miss US pageant, and documents a series of clips from that day, including more than three minutes of interactions between Trump, the Agalarovs and Goldstone.

Trump signed a deal with the Agalarovs to bring Miss Universe to Moscow in 2013.

It comes just a day after the US President’s eldest son used a Fox News interview to defend his meeting with the Kremlin-linked lawyer.

“In retrospect, I probably would have done things a little differently,” he told Trump supporter and presenter Sean Hannity.

“For me, this was opposition research.”

The President also defended Trump Jr as “innocent” after the interview, describing the controversy as “the greatest witch hunt in political history”.
